Propiconazole is a member of the DMI-fungicides group (demethylation inhibitors) These materials act on the fungal pathogen inside the plant at the stage of first haustoria formation and stop disease development by interfering with sterol biosynthesis in fungal cell membranes. Chlorothalonil has broad spectrum activity. It is believed that it deactivates several fungal enzymes (multiple-site action), therefore creating less resistance risk. Fludioxonil is a long lasting contact fungicide that provides broad-spectrum activity. It is believed to inhibit transport-associated phosphorylation of glucose, which subsequently results in the inhibition of fungal mycelial growth.
